“Belial,” taken from the Hebrew bĕlīya’al, meaning “worthlessness,” is a term used interchangeably with Satan. Actually, it is the name of another fallen angel whose sons took embodiment after the fall of Lucifer.
In the Old Testament, belial is usually interpreted as a common noun meaning worthlessness, ungodliness, or wickedness. (Deut. 13:13; Judges 19:22; 20:13; I Samuel 2:12; 10:27; 25:17; II Samuel 23:6; I Kings 21:10, 13; II Chronicles 13:7). In II Cor. 6:15, Belial is used as a proper name for a prince of demons.
Belial is described in Milton’s Paradise Lost as one of the fallen angels.
